Superplasticizer mainly absorbs on the cement hydrates covering the surface of cement particles instead of on the surface of unhydrated particles 超塑化剂主要是大量吸附在水泥颗粒表面的水化产物上而不是吸附在未水化水泥颗粒表面。
Screw bat type pre - plasticized installation , bigger capccity in piasticising , good quality in mixed refine , accuracy in measuring . minimum loss in injection pressure 螺杆式预塑装置,塑化能力大,混炼质量好,计量准确,注射压力损失小。
The major reason for the occurring of nonconformance between cement and superplasticizer lies in the fact that large amount of superplasticizer is absorbed by hydrates 水泥与超塑化剂相适应性不好主要是水泥水化产物吸附大量的超塑化剂所致。
You can choose the mode that switch inside the bushing . it can compensate the subsided distortion and makes the gas pipeline being all plastic 在钢塑转换施工方案技术的选择上,一般可选用套管内转换方式,既可抗拒一定的沉降变形,又可实现管网的全塑化。
The advanced barrier type screw rod and ikv squeeze out the system craft and the vacuum decides the diameter installment , guaranteed the raw material fully fuses , the plasticizing 先进的屏障式螺杆和ikv挤出系统工艺和真空定径装置,保证原料充分熔融塑化。
The thermoplastic materials can be plasticized to change its shape under high temperature and high shearing force . it is of good viscosity 热塑性塑料在高温及高剪切下可以塑化变形,具良好的流动性,可用一般注塑机加工,但冷却固化后坚硬而缺乏弹性,具循环可塑性。
Based on the shear theory of newtonian viscous liquid , the fusible damp coefficient is established for electromagnetism dynamic polymer extruder screw ' s axial vibration system 摘要对聚合物电磁动态塑化挤出机螺杆轴向振动系统,根据牛顿型粘性流体的剪切理论,确定了聚合物熔体的阻尼系统。
“ ecpcm ” is situated at the jiangsu province suzhou city taicang port development zone , which is near to yangtze river to the east , north to shanghai , and linked with kunshan and changshu in the west “华东国际塑化城”位于江苏省苏州市太仓港口开发区,东枕长江,南临上海,西北分别与昆山、常熟接壤。
The optimized process parameters are : the concentration of casting solution is higher than 9wt % , casting speed is 0 73m / min , temperature of wash bath is 45 and post - treatment is used 当铸膜液浓度在9wt以上,刮膜速度为0 . 73m min ,水洗浴温度为45 ,并增加热处理和塑化处理时,膜的分离性能较好。
